The Sangean CL-100 S.A.M.E. table-top all hazard alert radio is a Public Alert Certified weather radio and can receive all NOAA reports to notify people of severe weather advisories, watches and warnings conditions, civil emergencies, hazards and evacuation bulletins. The CL-100 can respond to emergency alert tones by activating a built-in audio or an external visual alarm (not supplied). The CL-100 has S.A.M.E. technology, the primary trigger for activating the US hazards and EAS (Emergency Alert System) used by commercial radio, television and cable TV outlets. S.A.M.E. allows you to screen unwanted or non-local alerts and filter distant warning broadcasts and monitor only those messages intended for your local area. For example if you live in a coastal county but not on the beach, you may not be interested in a coastal flood warning.
